They might be the most expensive rooms — without a view — in the city.

At $550,000 per year, suites in The Vault at the Brooklyn Nets’ Barclays Center arena offer exclusivity, high-end finishes and unmatched privacy — but no windows.

They’re for luxury tailgating.

“This is not for everyone,” Nets CEO Brett Yormark told The Post during an exclusive first look at The Vault’s 11 catacombs still under construction. “This is for a particular customer who wants to entertain at the highest level.

“Obviously, you don’t have a view of the game here, while every other suite you do. This is the pregame, postgame private entertainment space.”

Five of the suites have already been snapped up, Yormark told The Post.

Rap mogul Jay-Z, who is a Nets part owner and director of the arena, designed the suites and bought the first one — a glass-enclosed hive that stands to the right of imposing 15-foot-tall wooden doors to be emblazoned with a massive “V.”

“Jay-Z wanted every room to have a uniqueness to it,” Yormark added.

Other buyers include “high net-worth individuals” in finance and real estate, he said.

Suites feature dark hues accented by metallic flourishes, a bar/lounge area and a kitchen space. Each room will feature custom furniture and perforated metal lighting fixtures that mirror the arena’s exterior. A metallic glazing on two of the suite’s walls offers a one-way mirror effect.

Each room is roughly 300 square feet, and the lease comes with a minimum three-year commitment.

There are plenty of chances to mingle, too. Between the Vault suites is a common area that will feature a communal 2,400-square-foot champagne bar framed by a glowing bronze fabric overhead.

Each Vault suite comes with eight tickets in the first 10 rows for all Barclays events. Owners will also have access to a 24/7 concierge service, along with VIP parking.

Athletes and performers will pass directly by The Vault as they exit the court.

“It’s like your backstage,” Yormark said. “It’s the kind of environment where you are interacting potentially with celebrities.”

For now, orange hazard tape on a dusty concrete floor demarcates the asymmetrical shape of the suites, recognizable now only by their steel skeletons.

“This is hot!” Yormark said as he stood in Jay-Z’s unfinished suite.

The $1 billion, 19,000-seat arena at Flatbush and Atlantic avenues designed by AEcom/SHoP Architects will open Sept. 28 with a concert by Jay-Z. The Nets first home game will be in either late October or early November.

Team officials will hit the road this summer to market The Vault at a Hamptons estate.
